摘要
目的调查新兵长途徒步行军的肌肉损伤情况及维生素E对肌肉损伤的防护作用。方法选取50名男性新兵随机分为A、B、C、D、E组,每组10名。A、B、C组每天服用不同剂量的维生素E,D、E组口服等剂量的橄榄油,7 d后A～D组徒步行军,E组未徒步行军。徒步行军5 h后抽取静脉血测定其血清肌酸激酶(CK)与乳酸脱氢酶(LDH)活性。结果 CK与LDH活性E组明显低于其他4组(P<0.01),A、B、C 3组活性逐渐降低,且明显低于D组(P<0.01)。A组高于B、C组(P<0.01),但B、C两组间CK差异无统计学意义(P>0.05)。结论维生素E能保护长时间运动所导致的肌肉损伤。
Objective To observe condition of recruits＇ muscle injuries caused by walking march, and protective effect of Vitamin E on skeletal muscle injuries. Methods A total of 50 male recruits were randomly divided into group A, B, C, D and E, recruits in group A, B and C took Vitamin E by different dose every day, while recruits in group D and E took the same dose of olive oil. After 7 days, the group A-D finished walking march, but the group E did not finish it. The activity of serum creatine kinase （CK） and lactate dehydrogenase （LDH） in venous blood was detected 5 h after walking march. Results The activity of CK and LDH in group E was significantly lower than that group A-D （P 〈 0.01 ） , the activity of CK and LDH in group A, B and C was gradually weaker and significantly lower than that in group D （ P 〈 0.01 ）. The difference in CK between group B and C was not statistically significant （P 〉 0.05）. Conclusion Vitamin E may suppress the skeletal muscle injuries induced by continued exercise.
